Crank no start and very sluggish on crank?

Hi,

Is it possible for you to record it cranking and upload it for us to hear? Also, has the starter motor been checked to make sure it isn't failing?

If you have fuel and an ignition spark, the engine should run. However, things can prevent it from starting, such as low or excessive fuel pressure, low engine compression, a plugged exhaust system, and ignition/engine timing.

On the other hand, if it sounds sluggish when cranking, that leads me to believe it has something to do with the starter circuit.

If you remove a spark plug, are they wet? If not, try starting fluid to see if it makes a difference. We may have an injector issue, and fuel isn't entering the combustion chamber.

Do me a favor. Each fuel injector will have two wires. One of them at each injector is yellow with a black tracer. That is the power supply. With the key in the run position, confirm they are getting power. The other wire at each is a different color. The PCM provides a ground path via that wire to complete the circuit. If you do have power, confirm there is a signal ground while cranking.

I attached a schematic of the injectors below as a reference. I circled the power supply wires to each.

Let me know what you find. Also, if you could upload a video of it cranking for us to hear, it may be helpful. You could have a timing issue.

Let us know.

Take care,

Joe

See pic below.

It has a cracked engine block, they drove it for about 30 minutes without any coolant in it no compression at all, starter was changed also forgot to mention.

So the engine does not have any compression? it sounds like the engine is no good. Please go over this video.

Please go over this guide and get back to us.

None at all hoping it could be a head gasket but I don't think so warped cylinder head maybe or complete block is shot...

Yes per the video I did do the exact same test that was performed only mine isn't cranking fast jus sluggish enough to barely turn the pulleys and belt.

It sounds like the battery might be bad, I would take it into the auto parts store for testing. Can you upload a short video of the engine cranking so I can see?

Way more than that, I have a shop i mechanic out of, changed the battery, alternator, starter, belt, radiator, flush and fill with the coolant, changed oil, tested all fuses, relays and cleaned ground wires, diagnostic scan tool showed no codes and all live data readings were good...but finally after 5 or 10 trys cranking it you could see the oil on the dipstick changing to a more milky look and the radiator was shooting coolant with puffs of gas that smelled like smoke outta the radiator fill neck, bad head gasket I'm hoping or worse hope not...

Yep, that doesn't sound good.

This guide can help confirm the blown head gasket:

and this guide as well:

These will help us see if the engine needs repairs.

In the process of taking the head off now would have been easier to pull the entire motor out almost got to dismantle it all anyway just to get the cylinder head off.

I don't think so, most mechanics leave the engine in the car when doing a head gasket. Can you upload images of the problem you are having?

I've got it out, yes I usually leave it in also it's just a pain to get it out which the head looks good, the timing chain cover and the timing chain guide closest to the front of the car were broke and sheared the bearings on the crank, so got to pull motor anyway, that's what I told the customer at the beginning...

Nice work, sometimes the engine can come apart when they have high miles and something goes wrong, please use 2CarPros anytime we are here to help.
